The object of this invention is toprovide a fly paper supporting device of simple, du-

rable and comparatively inexpensive con-y struction.

A further object of my invention is to provide means for supporting a sheet of fly paper in position extended above surrounding objects, which I find is a much more effective position for accumulating flies on the fly paper, since they have a tendency to alight on raised objects rather than table tops, store counters, and the like.

More particularly, it is my object to provide a supporting frame with a drum rotatably mounted relative thereto and provided with means by which a sheet of iiy paper may be attached to or detached from the drum.

` Still a further object is to provide the supporting frame with a trough arranged below the ily paper drum for catching any of the sticky substance of the fly paper which may drop fr-om the paper when positioned on the drum.

I/Vith these and other objects in view my Ainvention consists in the construction, ar-

rangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claimsand illustrated in the accompanying drawings. Although thel invention is susceptible of a Variety of embodiments, it is unnecessary to fully describe and illustrate more than one in orderto give a full miderstamling of the invention both from its structural and functional standpoints. Accordingly, I have illustrated a preferred and desirable embodiment of the invention in the accompanying drawings in which: l

Figure 1 is a perspective view of my improved fly paper supporting device.

Figure 2 is a side elevation of the same, parts being broken away and other parts shown in section for illustrating the construction thereof.

Figure 3 is a detail sectional view on the line 3-3 of Figure 2; and

Figure l is an enlarged sectional view on the line Awel of Figure 3.

On the accompanying drawings I have used*V the reference character A to indicate generally, a supportingframe and B, a drum to which a sheet of iiy paper may be. affixed.

vThe supporting frame .A consists of end members 10,side members 12, and a bottom 5f .portion le spaced above.Y the bottom of the .supporting frame.

Each .end member 10 is provided with an outwardly depressed socket 1G preferably formed in the metal of the endA plate 10. The drum Bl consists of a cylindri- .n cal portion 18 and drum heads 20. The drum heads 20 may be soldered or welded in position relative to the cylinder 18,- or may be merely forced into position.

Each drum head 2O is provided with a hub .c 22 having a spindle pin 24 inserted therethrough and held. relative thereto by soldering or the like. The spindle pins 24fproject from opposite ends of the drum B, as clearly illustrated in Figure 2 of the drawings. The spindle pins 24 are adapted tobe received in the sockets 16 of the end plates 10 of the supporting frame A. It will be noted that the sockets 16 are arranged in such a manner as to be open at their upper ends, whereby the "f' drum B may be lifted for removing it from the supporting frame A. 1-

A sheet of fly paper 26 may be wrapped around the drum B and may be secured thereto in any desirable manner. On my drawings I have illustrated one end of the sheet 26 as being positioned on sharpened pins extending out of the drum cylinder 18.

The sheet 26 may then be wrapped around the drum B and lapped over the opposite end of the sheet as indicated at 30. The overlzqiping portion 30 is also pierced by the pins 28 and may be held in position relative to the pins to prevent its accidental removal therefrom by means of spring clips 32. The Eli spring clips 82 may be'secured to the drum l in any desired manner and are provided with openings Se to receive the pointed ends of the pins 28, as best shown in Figure 4.

Practical use of my device on the pins 28. The spring clips 32 may be raised by the fingers of the operator during this operation and after being released, will retain the paper in position. The drum B may be removed from or remain in position on the frame A, as found best suitable for performing the operations of removing onek sheet of iiy paper and' applying another.

In the summer time, when the temperature w is high, the sticky substance on the fly paper 26 sometimes has a tendency ton'relt and run down to the lowermost part of the drum and drip olf. To prevent such drippings from falling onto a table or the like,v I provide the bottom 14, Which together with the upper portions of the end members l() and the upper portions of the side members 12 forni a trough. v

Some changes may be made in the construction and arrangement of the parts of my de-V vice Without departing. from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modied forms of structure or use or' mechanical equivalents, Vwhich may be reasonably includ- `ed Within their scope.

I claim as my invention:

l. In a iy paper holder, a supporting 'frame having1 end members provided With depressions therein, a drum adapted to have a sheet Y of ly paper affixed thereto, spindles on said drum extending into said depressions, said supporting frame having sides with their ends connected to the side. edges of said ends and a partition between the topand bottoni of the frame to provide a trough below said drum.

, 2. In a Hy paper holder, a su} 9port,fa drum mounted thereon, andmeans for securing a 4g sheet of fly paper around said drinn, said means comprising sharpened pins and'V clips adapted to engage overlapping ends of the fiy paper. Y
